Change default ldap scheme
by Andrew Radygin 07 Dec '17

07 Dec '17

Hello everybody, I want to know, is there possibility to change default ldap scheme, where user and groups are storing. For instance, I have: cn=USER, cn=groups, cn=accounts, dc=domain,dc=net cn=GROUP-OF-USERS, cn=groups, cn=accounts, dc=domain,dc=net It seems to be too straightforward. Can I change it to cn=USER, cn=groups, cn=accounts, dc=domain,dc=net cn=GROUP-OF-USERS, cn=org-groups, cn=accounts, dc=domain,dc=net ? Or to do any other corrections of ldap scheme for placing different objects. Thanks!

User's personal group not resolving
by Aaron Hicks 06 Dec '17

06 Dec '17

Hello the list, We imported all our users with uidnumbers from our old LDAP, but their gidNumber was from 4 groups. This caused us issues with users wanting to grant access to personal spaces to one user, but instead granting access to all the members of the group. To resolve this, when they were imported into FreeIPA we assigned them all new gidNumbers, as reusing their uidNumbers caused large number of gidNumber clashes as many groups were assigned from the same integer range. So now we have a log of users with uidNumber 5XXX and gidNumber 5000XXX. When they log in they see an error like this: /usr/bin/id: cannot find name for group ID 100019 It's pretty much because their gidNumber != uidNumber So getting all the name and group details: [username@ipaserver01:~] $ id username uid=5807(username) gid=100019 groups=100019,66400035(group1),66400007(group2),66400012(group3),66400044(gr oup4),175321(group5),2075295(group6),66400046(group7) [username@ipaserver01:~] 2 $ id -g username 100019 [username@ipaserver01:~] $ getent group 5807 username:*:5807: [username@ipaserver01:~] $ getent group 100019 [username@ipaserver01:~] $ Now, the last part, we can't change their uidNumber. We have a massive filesystem (many terabytes) backed by a tape library (many petabytes) so we need their uidNumber to match that file archived to tape in 1987 and migrated through our tape system upgrades :P So the question is; can we make it resolve those gidNumbers? .I could make 2,500 groups for 2,500 users. Regards, Aaron

Guide to enabling CA?
by Bret Wortman 06 Dec '17

06 Dec '17

Is there an online guide to turning on a CA? We had one, which signed all our SSL Certs and such. It worked quite nicely. Then we rolled an upgrade around our IPA servers to get them from Fedora to Centos, and in the process, we failed to migrate the CA, so we ended up with 3 servers without a CA. Fast-forward to today, and we lost one, which was our intended CA. So now I have two servers (a and z) which are working just fine but we can't create new SSL certs signed by our IPA CA. How can I go about promoting one of these to CA? I know I followed online directions the last time, but that was years ago and I've lost the link. Thanks! It's a private development network, so relying on external CAs isn't an option. -- photo *Bret Wortman* President, Damascus Products LLC 855-644-2783 <tel:855-644-2783> | 303-523-8037 <tel:303-523-8037> | bret(a)damascusproducts.com <mailto:bret@damascusproducts.com> | http://damascusproducts.com/ | 10332 Main St Suite 319 Fairfax, VA 22030 <http://facebook.com/wrapbuddiesco> <http://twitter.com/wrapbuddiesco> <http://instagram.com/wrapbuddies> <https://facebook.com/wrapbuddiesco><https://instagram.com/wrapbuddies>

openvpn authenticating to freeipa
by Andrew Meyer 06 Dec '17

06 Dec '17

Hello, I am trying to configure my openvpn setup to authenticate against FreeIPA. I have OpenVPN configured and is accepting connections. The package for ldap_auth is installed and configured. However I have tried to setup anonymous ldap lookups and authenticated ldap lookups and neither seem to be working. Every time I change the config to test openvpn works just fine. However when I try to connect to the VPN it tells me that the LDAP bind failed w/ invalid credentials. I have been combing through google and found that a few people used pam in the past and still do today. Is this proper procedure for setting this up? Is there a similar pam module that I could copy/link? Thank you, Andrew

When I add a new server to FreeIPA, and it fails to add DNS, is there a way to go back and rerun a script to add all the records needed?

Re: Unable to create GSSAPI-encrypted LDAP connection
by Aaron Hicks 04 Dec '17

04 Dec '17

Hello the list, It looks like sssd's horrible logging messages were to blame. It looks like when the keytab was initially deployed the system time between the IPA server and the host were not quite in sync and the keytab was invalidated. I redeployed the host's keytab (which because SLES lacks the ipa-client tools, had to be done on the IPA server and delivered via SCP) and the problem was resolved.

Authentication for ipa cli scripting (wsgi, kerberos)
by skrawczenko＠gmail.com 04 Dec '17

04 Dec '17

Hello all, i suppose the issue is quite typical but still unable to find any solution. All i need is to run some ipa cli commands from scripts with preliminary kinit I manage to authenticate as kinit -F -k -t <keytab> <principal> That allows me to use ldap for example, i can do ldapsearch -Y GSSAPI etc However, when trying to run cli commands, i'm getting the following sh-4.2# ipa user-find aaa ipa: ERROR: cannot connect to 'any of the configured servers': https://<idm0>/ipa/json, https://<idm1>/ipa/json This is caused by wsgi module, as it said in httpd error log [Mon Dec 04 06:45:45.027199 2017] [:error] [pid 1745] ipa: ERROR: 500 Internal Server Error: KerberosWSGIExecutioner.__call__: KRB5CCNAME not defined in HTTP request environment [Mon Dec 04 06:45:45.027769 2017] [:error] [pid 1745] [remote ...:60] mod_wsgi (pid=1745): Exception occurred processing WSGI script '/usr/share/ipa/wsgi.py'.

IPA has been upgraded to latest 4.5.0, wsgi module after yum update is Name : mod_wsgi Arch : x86_64 Version : 3.4 Release : 12.el7_0 Size : 197 k I never configured anything manually, so barely broke anything. Please any ideas
